generators, wherein a bleaching agent 1s" generated or compounded andconveyed to a bolting machine or flour chute, onto a point of contactwith flour whereby the same can be bleached.

The object of my invention is to provide a simple, durable andinexpensive generator wherein novel means is employed for automaticallycontrolling the process by which a bleaching agent is liberated or setfree.

The above and other objects are attained by a generator that will behereinafter` specifically described and then claimed, and reference willnow be had to the drawing, Wherein y Figure 1 is an elevation ofv oneside of the generator; Fig. 2 is a similar view of the other side,partly broken awa and partly in section, and F ig. 3 is a plan o thegenerator.

A generator in accordance with this invention comprises a rectangularcasing having a base 1, side Walls 2 and 3 and end walls 4 and 5supporting a top plate 6. rlhe side walls 2 and 3 are extended beyondthe end wall 5, the extension being ofless height than the side walls tosupport an auxiliary top plate 7. 'llhe extensions of the side walls- 2and 3 are connected by an auxiliary end wall 8 having a hinged door 9,and said door, the auxiliary top plate 7, the auxiliary end wall 8, andthe extension of the walls 2 and 3, coperate in providing a rectangulargenerating chamber 10 at an end of the caslng. Y

ln the upper part of the casing and connecting the side Walls 2 and 3are horizontal and vertical partitions 11 and 12 and these partitionsare connectedby a Vlongitudinal partition 13. These partitions pro-Specication of Letters Patent.

verse driven shaft 18. This shaft has one end thereof provided with apulley 19 and a flan ed belt wheel 20, while at the opposite4 end of theshaft is a large flanged belt Wheel 21. It is through the medium of thepulley 19 that the shaft 18 can be driven by a motoror from a suitablesource of power.

Journaled in the side walls 2 and 3 and extending transversely of thecompartments 14 and 15 is a fan Yshaft 22 having a fan or bladed wheel23 within the compartment 15 and a small flanged belt wheel 24 at theouter side of the wall 2. A belt25 is trained over the belt wheels 21and 24 whereby the fan 23 can be driven within the compartment 15.

The side Wall 3 supports a revoluble shaft 26 and mounted upon saidshaft is a large flanged belt Wheel 27 over which is trained a belt 28that passes around a small belt wheel 20.A The belt wheel 27 is providedwith a pivoted bar 29 having an end thereof adjustably connected to aslotted web 3() of the wheel 27. The bar 29 supports a Wrist pin 31 andconnected to said pin is a pitman 32.

Mounted upon the top of the auxiliary plate 7 is a feeding device,comprising a base plate 33, sets of bearings 34 and shafts 35 rlheseshafts support a train of gears 37 and the shaft 35 has an end thereofprovided with a ratchet wheel 38 and a ratchet arm 39.

. The ratchet arm 39 has the outer end thereof pivotally connected, asat y40 to the pitman 32 and said ratchet arm is provided with a gravitypawl or dog 41 'normallyengaging the ratchet wheell 38, whereby saidratchet Wheel and the shaft 35 can be .intermittently moved by thedriven belt wheel 27.

One end of the shaft 36 has a gravity dog 42 normally engagingtheratchet Wheel 38 to prevent a counter clockwise movement of the shaft35 as the gravity pawl 41 moves over the same to obtain a fresh gripupon the ratchet wheel. The opposite end of the shaft 36 is providedwith a grooved wheel 43 confronting a Wheel or roll 44 revolublysupported by a resilient arm 45 connected to the base plate 33. TheWheels 43 and 44 constitute feed rolls for a metallic rod or galvanizedWire 46, which is guided through an opening 47 in the auxiliary topplate 7 to enter a receptacle 48 in the generating chamber 10 of themachine. rl`he receptacle 48 is graduated and is adapted to containchemicals, which when combined with the metallic element, as the rod 46,liberates a bleaching gas or agent, as nitric oXid, that is drawnthrough the opening 16 into the compartments 14 and 15 by the fan 23 andis conveyed t0 a desired point by a conduit 49 communicating with anopening 50 in the top plate 6. Another opening 51 in the side Wall 2admits air to the generating chamber 10 of the machine.

From the foregoing it Will be observed that the feeding mechanism abovethe generating chamber 10 controls the use of the bleaching fluid in thereceptacle 48 and the process by which a bleaching agent is set free.The feeding of the metallic element 46 into the bleaching fluid can beregulated by adjusting the Wrist pin bar 29 of the belt Wheel 27, andthe operation of the generator ing having 'a generating chamber at oneend thereof and communicating compartments therein, a receptacle in saidgenerating chamber adapted to contain chemicals, an intermittentlyactuated feeding mechanism above the chamber of said casing and adaptedto feed and guide galvanized Wire into the fluid Within said generatingchamber to liberate nitric oXid, a fan shaft through the saidcompartments in said casing, a fan on said shaft in one of saidcompartments adapted t0 draw the bleaching agent from the generatingchamber into the fan compartment and force the same to a point remotefrom said generator, a driven shaft supported by said casing at the endopposite the generating chamber adapted to 0perate said fan shaft, arevoluble Wheel at the opposite side of the generator adapted to havemovement imparted thereto by said driven shaft at one side of saidgenerator, an adjustable pivoted bar carried by said Wheel, and a pitmanconnected to said bar and adapted to operate said feeding mechanism.

In testimony whereof I aiiix my signature in presence of two witnesses.
